Can you guide me about the connection between mongodb and power bi through ODBC driver. I have connection between them. but i got unexpected errors like:
"OLE DB or ODBC error: Exception from HRESULT: 0x80040E4E." , "OLE DB
or ODBC error: [DataSource.Error] ODBC: ERROR [42S22] [MySQL][ODBC
1.4(w) Driver][mysqld-5.7.12 mongosqld v2.14.3]Unknown column 'COD' in 'field list'."
and
"DataSource.Error: ODBC: ERROR [08S01] [MYSQL][ODBC 5.3(w) Driver Lost
conection to MySQL server at 'waiting for initial communication
packet', system error: 10060".
Can you tell me where the problem and how can I overcome on it?
I've had the same problem, try to go over the below steps and take a look at my advice under the fourth point (4).
Install mongosqld on your server based on your OS (first prerequisites).
LunchBI connector:
a) Make logs folder and mongosqld.log file in it.
b) Setup mongosqld.conf (IP:<your_server_ip>, PORT:3307)
Install mongosqld as a System Service link
Create a system DSN on your computer based on your OS, link.
Hint: On Windows (in ODBC data source) try to make both ANSI and UNICODE
connectors and do not forget to select a database in the dropdown menu.*
e.g. connect to Mongo via PowerBI via ODBC
a) Select a connector
b) Select the database, that you have selected in the previous dropdown menu.
For more information follow the official guide
you have to install mongosqld on your server and configure the .yalm file.
Inside it you have to uptade 'bind ip' field, by adding the remote ip.
I need to backup my DB so I use Tools --> Database Export.
However, when I want to choose my connection I got no connection in drop down list.
Just to mention that I can see my connection list in "Connections" tab and also all connections in "C:\Users{MyUser}\AppData\Roaming\SQL Developer\system3.0.04.34\o.jdeveloper.db.connection.11.1.1.4.37.59.31\connections.xml" file
Same behavior happens also in "Database Copy", "database Diff" and in "Monitor SQL"
Any idea ?
Thanks in advance
The Database Export feature is built for Oracle Databases only. That's why you aren't seeing your DB2 connections in the Export, Copy, or DIFF wizards in ORACLE SQL Developer (keyword, Oracle).
If you want to backup your IBM DB2 database, you need to use the tools that IBM gives you for managing DB2.
Running any sort of query on pgAdmin 4 just returns a 'table_oid' under messages.
I am able to get the necessary data when running the query from the command line, for example
SELECT ST_MakePolygon(ST_GeomFromText('LINESTRING(75.15 29.53,77 29,77.6 29.5, 75.15 29.53)'));
I understand that table_oid refers to the object id of the table, but I have no idea how to access it.
Pardon me please if it is a simple question, but I am unable to find any resources online
Expected:
010300000001000000040000009A99999999C9524048E17A14AE873D4000000000004053400000000000003D4066666666666653400000000000803D409A99999999C9524048E17A14AE873D40
Actual:
table_oid
From pgAdmin 4 project tracker:
Temporary solution until next release and tested in my ubuntu 18.04 machine:
Replace these two 2 files:
/usr/share/pgadmin4/web/pgadmin/tools/sqleditor/__init_*_py
/usr/share/pgadmin4/web/pgadmin/tools/sqleditor/command.py
Link to files:
__init_*_.py
command.py
Note:
The first file's name is __init_*_py, without the *.
Try Squirrel SQL - Universal SQL Client. It's an extremely useful SQL client. I use it to access SQL Server, PostgreSQL, MySQL, Access. It's not as good looking as pgAdmin4.
Install JAVA first, if not already installed.
Install Squirrel SQL.
Download the latest PostgreSQL JDBC driver, e.g. postgresql-42.2.6.jar, and put it into a convenient location.
Open/Start Squirrel.
Click the Drivers Tab and scroll down to PostgreSQL. Double click PostgreSQL. A "Change Driver: PostgreSQL" dialog box/window will open.
Click the Extra Class Path tab and click the Add button. Navigate to and choose the PostgreSQL JDBC Driver that was downloaded in step 3. above.
Click the List Drivers button, "org.postgresql.Driver" should appear in the Class Name drop down box.
Click OK.
Setup PostgreSQL JDBC Driver
The driver should now be setup.
Click the Aliases tab to setup a connection to your database. See my example screenshots.
Setup Database Connection
I am relatively new to Redshift but have used the SQL Server Management Studio(SSMS) to work with SQL Server.
Now I have a project with Redshift and am using the SQL Workbench to query the Redshift Cluster.
However I dont find an Object Explorer kind of window on the SQL Workbench interface. Is there such a window on the SQL workbench?
Also, how do i select the active Redshift database on the SQL Workbench?
Used to be pretty simple in SSMS(Select the active database from a drowp down option list), but i am lost when it comes to SQL Workbench?
Thanks!
The comment above from #a_horse_with_no_name is correct. The tab you're trying to find is called "Database Explorer" and it can be opened Tools -> Show Database Explorer.
Credit goes to #a_horse_with_no_name for answering first.
I'm trying to connect to a PostgreSQL 9.1 database using Oracle SQL Developer 3.0.04, but I'm not having any success so far.
First, if I add a third party driver on preferences, when adding a new connection there's no tab for PostgreSQL (it works fine for MySQL though). I'm using a JDBC4 version 9.1 driver, but I tried a JDBC3 of the same version and still get the same thing.
Second, there's nothing like manual configuration tab when adding a new connection. The closest is the Advanced option on Oracle tab, where I can provide a custom URL, but it fails because complains about the selected Driver (of course).
Finally, I got connected importing a connection from an XML file (contents below), but it displays only my schemas and doesn't show my tables inside them.
So, my question is: does Orable SQL Developer support PostgreSQL connections? Is there any other way to have my tables being displayed in the ObjectViewer?
<?xml version = '1.0' encoding = 'UTF-8'?>

Oracle SQL Developer 4.0.1.14 surely does support connections to PostgreSQL.
download JDBC driver for Postgres (http://jdbc.postgresql.org/download.html)
in SQL Developer go to Tools → Preferences, Database → Third Party JDBC Drivers and add the jar file (see http://www.oracle.com/technetwork/products/migration/jdbc-migration-1923524.html for step by step example)
now just make a new Database Connection and instead of Oracle, select PostgreSQL tab
Edit:
If you have different user name and database name, one should specify in hostname: hostname/database? (do not forget ?) or hostname:port/database?.
(thanks to #kinkajou and #Kloe2378231; more details on https://stackoverflow.com/a/28671213/565525).
I've just downloaded SQL Developer 4.0 for OS X (10.9), it just got out of beta. I also downloaded the latest Postgres JDBC jar. On a lark I decided to install it (same method as other third party db drivers in SQL Dev), and it accepted it. Whenever I click "new connection", there is a tab now for Postgres... and clicking it shows a panel that asks for the database connection details.
The answer to this question has changed, whether or not it is supported, it seems to work. There is a "choose database" button, that if clicked, gives you a dropdown list filled with available postgres databases. You create the connection, open it, and it lists the schemas in that database. Most postgres commands seem to work, though no psql commands (\list, etc).
Those who need a single tool to connect to multiple database engines can now use SQL Developer.
Oracle SQL Developer doesn't support connections to PostgreSQL. Use pgAdmin to connect to PostgreSQL instead, you can get it from the following URL
http://www.pgadmin.org/download/windows.php
I managed to connect to postgres with SQL Developer.
I downloaded postgres jdbc driver and saved it in a folder.
I run SQL Developer -> Tools -> Preferences -> Search -> JDBC
I defined postgres jdbc driver for the Database and Data Modeler (optional).
This is the trick.
When creating new connection define Hostname like localhost/crm? where crm is the database name. Test the connection, works fine.
If there is no database with the same name as the username, then clicking "Choose Database" will fail with an error like "Status : Failure -FATAL: database "your_username" does not exist"
To work around this, put 5432/database_name? in the Port field, where 5432 is the port of your Postgres instance and database_name is the name of at an existing database that your_username has access to. Then click "Choose Database" again and it should work. Now you can choose the database you want and remove the extra /database_name? from the Port field.
I think this question needs an updated answer, because both PostgreSQL and SQLDeveloper have been updated several times since it was originally asked.
I've got a PostgreSQL instance running in Azure, with SSLMODE=Require.
While I've been using DBeaverCE to access that instance and generate an ER Diagram, I've gotten really familiar with SQLDeveloper, which is now at v19.4.
The instructions about downloading the latest PostgreSQL JDBC driver and where to place it are correct. What has changed, though, is where to configure your DB access.
You'll find a file $HOME/.sqldeveloper/system19.4.0.354.1759/o.jdeveloper.db.connection.19.3.0.354.1759/connections.json:
{
"connections": [
{
"name": "connection-name-goes-here",
"type": "jdbc",
"info": {
"customUrl": "jdbc:postgresql://your-postgresql-host:5432/DBNAME?sslmode=require",
"hostname": "your-postgresql-host",
"driver": "org.postgresql.Driver",
"subtype": "SDPostgreSQL",
"port": "5432",
"SavePassword": "false",
"RaptorConnectionType": "SDPostgreSQL",
"user": "your_admin_user",
"sslmode": "require"
}
}
]
}
You can use this connection with both Data Modeller and the admin functionality of SQLDeveloper. Specifying all the port, dbname and sslmode in the customUrl are required because SQLDeveloper isn't including the sslmode in what it sends via JDBC, so you have to construct it by hand.
I got the list of databases to populate by putting my username in the Username field (no password) and clicking "Choose Database". Doesn't work with a blank Username field, I can only connect to my user database that way.
(This was with SQL Developer 4.0.0.13, Postgres.app 9.3.0.0, and postgresql-9.3-1100.jdbc41.jar, FWIW.)
Oracle SQL Developer 2020-02 support PostgreSQL, but it is just the basics by adding postgreSQL driver under jdbc dir and configure by adding as a 3rd party driver.
The supported functionality:
multiple databases which can be selected at connection definition
CRUD operations like query tables
scheme operations
basic modelling support: show tables without pk, fk, connections
Not supported functionalities:
no table or field completion
no indexes are shown in a tab
no constraints are shown in a tab like: fk, pk-s, unique, or others
no table or field completions in the editor
no functions, packages,triggers, views are shown
The sad thing is Oracle should only change the queries behind this view in case of PostgreSql connections. For example for indexes they need to use this query: select * from pg_catalog.pg_indexes;
Except that it will not work if your user name and database name are differents. It sounds like an SQLDeveloper bug and i can't find any workaroud
Maybe there are some bugs in Oracle SQL Developer when it connect to the postgresql.However I connect postgresql with navicat successfully.(My postgresql username and database name are different
host= localhost/postgres? worked for me if you need a schema/database use:
localhost/postgres?currentSchema=myschema
ex: localhost/postgres?currentSchema=public
once connected, you can also use the
[Choose Database] button and pull down
sql developer postgres jdbc url for the rest of us
